Hi Vincent and Dickson,
I enjoy TWIP, and often recommend it to my students. I'm a parasitologist, primarily a Leishmaniac, but I have learnt a lot from TWIP. I find it both more educational and entertaining than Car Talk.
The disc... Read More

ANYONE who walks in the woods will be familiar with witches’ brooms (pictured). Many trees sport these bushy tumours, which have a variety of causes. An important one is a group of bacteria called phytoplasma that are, in turn, carried from plant to plant by sap-sucking insects such as leafhoppe... Read More

I listened to the latest TWIP this morning. Dickson mentioned the herbicide atrazine but thought it was a fungicide. It is actually a herbicide in the photosynthesis inhibitor class. Another bit of trivia about ag chemicals is that old chemicals like ... Read More
Jessica Galloway-Peña, Ph.D., fellow in the Department of Infectious Diseases, Infection Control and Employee Health at The University of Texas MD Anderson Cancer Center and her colleagues have shown that disruption of the microbiome by illness or the administration of therapeutics can often lea...

When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More
